IPC: H03K19/086
Filed: 1978-01-26
Abstract: PURPOSE: To improve the DC and AC performance of various integrated circuits, by using transistors which can conventionally select the base-to-emitter forward voltage, in logic circuits.  
     CONSTITUTION: The collector of the multi-emitter transistor QR 1  having a plurality of emitters E having different areas is grounded, the base is connected to the reference voltage VR, and the reference voltage suitable for Va input is obtained by connecting parallel the emitters E 1  and E 2 , then E 1  and E 2 . E 1  and E 2  are simultaneously connected to VaR and the reference voltage suitable for Vb input is obtained from the emitter E 3 , then this is connected to VbR. Thus, since the number of signals is different for each case, the reference level always close to the suitable value can be fed to each input, by designing the transistor QR so that the base to emitter forward voltage required can be obtained with the combination of emitters in advance to the input group not uniform for the logic amplitude.

Filed: 1986-01-22
Abstract: PURPOSE:To correct the deviation of both optical axes of an objective lens and an irradiated optical axis of an optical system leading a luminous flux to the said objective lens when an optical pickup is mounted tiltly by arranging both the axes with the deviation in advance. CONSTITUTION:A light beam from a laser diode 1 is reflected totally at a right angle by a reflection prism 4 and projected onto an optical disc by an objective lens 7. Then the reflected light from the optical disk is progressed reversely to the said optical path, reflected in a polarization film and detected by a photodetector 9. In order to correct the displacement of the lens 7 due to the tilted mounting of the optical pickup, the optical axis O1 of the lens 7 and the irradiated optical axis O2 of the optical system leading the luminous flux are deviated in advance so that the lens 7 is located reversely to the direction of displacement by a nearly equal quantity to the displacement in the horizontal state. Thus, in mounting the optical pickup tilted at a prescribed attitude, tracking plate springs 26a, 26b are deflected to displace the lens 7, the axes O1, O2 are nearly made coincident and the optical characteristic is ensured regardless of the tilted attitude.
